Wierd looking oil?? Ideas??

Definitely some sort of contamination to change color that much. New oil usually has a slight amber tint to it. Looks like water in the oil to give it that color. If you have a leaky head gasket you might see some white smoke from the exhaust. Diesel in the oil wont change the color much but will thin it down noticeably and raise the oil level in the engine.
With that much color change I would change the oil and watch for color change, oil level change and water level changes. How long since the oil was changed?

Condensation from the cold nights and warm days?

Looks like water to me.

looks like water to me too, kinda scary... coolant is full though you'd think it would be low. hasn't been ran for a few months. looks like oil change. I might just leave the oil plug out till I need to run it and see if any coolant drains out....

Crawl under it - unscrew the drain plug SLOWLY - it should begin to leak, water will be the first to appear IF you have not stirred things up by running the engine.

Would take a lot of condensation to make that much water in the oil. Did it have anti-freeze at sufficient strength for conditions?

Dad had a 9G D7 with starting engine putting water into its crankcase - cracks in waterjacket - does not take much water to make oil very "milky".

The company I used to work for ran ATF in hyd. systems ,they said it didn't get as thick as hyd. oil in cold weather. someone may have used it to thin the oil.

It also doesn't take a real long time of sitting for the water to separate to the bottom. I had a D2 that had an internal coolant leak and I would drain the coolant off the bottom of the pan using the drain plug until fresh oil came out if I had to run it at all before I repaired it. Coolant can eat up bearings in a short time.

yep, drained the oil today... found water. wasn't a lot but enough to cause problems. looks like I have problems ahead of me... grrr
